I'm using FM13 on my office PC and FM go on my Ipad. Had no problem accessing and updating records via FM go while in my office or in my home but when I made changes to a record in the field the first time I got the following error message "Your record changes cannot be saved because this record was modified by another user while you were disconnected. Revert / Cancel" Selecting either Revert or Cancel does nothing. Cannot select another record or close the existing record without the error message popping up again so FM go is unusable. The changes I made on FM go from the field did not appear on the record on the office computer.
